We are using Hubspot API to capture form fills from our web forms and we have recently noticed that certain domains are getting blocked by Hubspot. We have a form validation on our website forms side which should be the final check/ true source of info. So is there a way to turn this off from Hubspot’s side? These are the domain examples I had tested with:

- [testTwoPartFormxyz.com](http://testTwoPartFormxyz.com)

- [testtwopartformxyz.com](mailto:erik@testtwopartformxyz.com)

Hi @AnjaliM

Not sure why that would be happening… could it be a check to see if the domain name has been registered? That would be an easy check and good for blocking that type of spam. If (and, that’s if) HubSpot is checking domain validity I wouldn’t turn it off even if I could.

We typically use [Mailinator](https://www.mailinator.com/) (email equivalent of a burner phone) for testing forms - you get the benefit of a valid email address and you can check the replies.

Have fun

Mike
